Data batch direct download service (WFS): Rhone Technology Risk Prevention Plans (RTPP)

Risk Prevention Plans (RPPs) are the key government instrument for risk prevention. Their objective is to control development in areas at risk. The development of a risk prevention plan generates a set of spatial data organised into several data sets. The same PPR may include spatial datasets containing: — main scopes of the RPP; — restricted areas of the plan once approved. RPP regulations generally distinguish between ‘construction ban areas’, so-called ‘red areas’, where the hazard level is high and where the general rule is the construction ban; ‘areas subject to requirements’, known as ‘blue zones’ where the hazard level is medium and projects are subject to requirements adapted to the type of issue and areas not directly exposed to risks but subject to prohibitions or prescriptions; — hazard areas represented on the map of hazards used for risk analysis by crossing with the stakes, specifying for each zone the level of the hazards to which it is exposed; — issues which are persons, property, activities and elements of cultural or environmental heritage threatened by a hazard and likely to be affected or damaged by it; — origins of risk, i.e. the entity of the real world which, through its presence, represents a potential risk. This entity may be characterised by a name, a reference to an external object or a geographical object that locates the actual entity causing the risk. Each element in the same PPRN dataset is bound by the GASPAR format identifier “ddd[PREF|DDT|DDT|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and the order number of the PPR procedure associated in GASPAR) to a single object in the PPRN document table described by the N_DOCUMENT_PPRN metadata sheet.风险预防计划（Risk Prevention Plans, RPPs）是政府开展风险预防工作的核心工具，其目标为管控风险区域的开发活动。 风险预防计划的编制会生成一系列空间数据，并划分为多个数据集。同一份风险预防计划可包含以下空间数据集： — 风险预防计划的核心范围； — 计划获批后的限制区域。风险预防计划的监管规范通常区分以下类别：其一为‘禁止建设区’（又称‘红区’），此类区域灾害等级较高，普遍适用禁止建设的规则；其二为‘条件管控区’（又称‘蓝区’），此类区域灾害等级为中等，项目需遵循适配问题类型的管控要求；此外还有部分区域虽未直接暴露于风险之中，但仍需遵守禁令或管控条款； — 灾害影响区域：指通过与受险要素叠加开展风险分析的灾害分布图上所标注的区域，且明确标注各区域所面临的灾害等级； — 承灾载体：即受灾害威胁、可能遭受影响或损毁的人员、财产、生产活动，以及文化或环境遗产要素； — 风险源：即现实世界中因其存在而构成潜在风险的实体。该实体可通过名称、外部对象引用或用于定位实际致险实体的地理对象进行标识。 PPRN数据集（PPRN）中的每个元素均通过GASPAR格式标识符"ddd[PREF|DDT|DDT|DREAL]aaaannnn"（其中AAAA与NNNN分别对应GASPAR系统中关联的风险预防计划流程的参考年份与序号），与由N_DOCUMENT_PPRN元数据表所描述的PPRN文档表中的单个对象绑定。
